FLYER consrnuc'rronron THREADSPINNING AND 'rwrs'rmo mwrrs.

Application filed December 13,1926. Serial No. 154,575. 1

y This invention relates to a flyer construction tor thread spinning and twisting units of the character shown and described in my Patent No. 1,569,831, granted to me on November 11, 1924, as well as in acopending application upon a spinning and twisting machine, Serial No. 154,577 filed December 13, 1926.

The primary object of this invention is to provide a rigidly balanced Ilyer wherein the same may be readily removed from or positively attached to the spindle of the spinning and twisting unit, and wherein the fiyer thread receiving armmay be easily and rapidly detached from the flyer body to per-..

mit the renewal or repair of the same.

A still further objectis to provide a device of this character wherein the body attaching end of said thread receiving arm is so formed with respect to the body as to become securely locked thereto as soon as properly associated therewith, and this without requiring any outside agency.

The invention 'turther aims to provide a flyer including aslngle thread receiving arm Y having balancing means in opposed relation with the arm so I thatthere will be absolutely no vibration of the spinning and twisting unit spindle especially at high speeds thereof.

i A turther'salient object is to provide a.

readily detachable thread guide eye for the thread receiving end of the fiyer arm so that the same may be renewed when necessary.

Other objects will become apparent as the 0 nature of the invention is better understood,

the same comprising the novel form. combination and arrangementof parts hereinafter morefully"described, shown in the accompanying drawing and claimed.

In the drawing wherein there is disclosed;

two embodiments of the invention,

Figure 1 is a tragmenta-ry view. partly in section and partly in elevation of a. thread spinning and twistingunit as fully shown and described in my said patent and copend} ing application, thespindle thereof being equippedwith a fiyer constructed in accord ance with the present invention.

Figure 2 is tin-enlarged longitudinal sec tion taken substantially ,upon the line 2-2 of Figure 1.

Figure 3 is a section taken at right angles through the device as disclosed in Figure 2.

Figure 4 is an inner side elevation of the fiyer. p I

Figure 5 is an inner side elevation of a slightly modified form of the invention, and

through.

First having reference to Figures 1 to 4 1nelus1ve,'the spindle of the spinning and twisting unit is designated A while the form of the improved flyershown in these figures is designated generally by the rat Said flange 8 is formedwith an opening 9 through which a radial thread guide arm 10 passes, which arm is. in the form of a length of steel wire asindicatedin the drawmg. The inner end of thiswire is so bent as at 11 toenga-ge around the major portion of the collar 7,'Wl1ll the extreme end of the wire is bent laterally outwardly to provide a locking pin 12, that is to be forcily engagedwithin a. slot 13 of saidflange 8. 'rhesloth r s p o ninety grees from the flange opening 9, while the curved portionfll of the wire normally tends to expand away from the collar with the result that/the pin 12 is frictionally heldwithin the slot inan obvious manner.

However, the Wire may be readily removed ,from the spindleattaching plate 5 by forcibly releasing the pinfrom the slot and then threading the end of the wire through the flangeopening 9. p

The extreme outer end of the wire is so bent upon itself as to provide a relatively oval shaped longitudinal eye 11. This eye is normally'closed by reason of the end of the bent overportion of the wire, which partially forms said eye, being bent ast the wire arm proper-as clearly disclose Figures 1 and 4. This eye l lis provided for the purpose of permitting of the rapid attachment of a relatively small porcelain sleeve 15 through which the thread from the spindle. A is extended as indicated in Figure 1. .By reason ofthis porcelain.sleeve, .the

thread does not come into contact with the wire arm which would otherwise result in the weakening and cutting of the thread. Obviously, when it is desired to remove this thread guide sleeve, it is only necessary to forcibl pull downwardly upon the same for springing the outer portion of the eye away from the flyer wire proper. On the other hand, one of these guide sleeves may be readily associated with the eye by merely placing the same upon the end member of the eye and then forcing upwardly thereon. As soon as the sleeve is associated with the wire eye as indicated in Figures 1 and 4, this eye will assume the locking position disclosed in said figures.

For counterbalancing the weight of the flyer arm, there is disposed between the flange 8 and collar '4' in opposed relation with the opening 9 in said flange 8, a weight 16 preferably in the form of a rectangular block of metal that is former centrally with a threaded opening that will register with an opening in the collar 7 and an enlarged opening in the flange 8 when said weight is disposed between the flange and collar as more clearly disclosed in Figure 3. For securing this weight to the flyer and for providing means of attachment of the flyer to the spindle A, a screw 17 is threaded into the opening of the weight, the inner end of the screw being enga ed within the opening of the collar 7 so t at the screw may be forced into engagement with the spindle for locking the flyer thereon. Obviously, the large opening in the flange 8 permits access to the headed end of the screw so that the same may be turned by a screw driver.

In the form of the invention disclosed in Figures 5 and 6, the same consists of a relatively large sheet metal plate 5' flanged circumferentially at its edge as at 8. The center of this plate 5 is formed with an opening for receiving one end of a sleeve 7 that is formed inwardly of the end engageable through the opening in the plate with a circular flange 18, the inner face of which is forced into engagement with the plate 5' after which the end of the sleeve projecting through the opening is turned over to rigidly connect the sleeve to said plate, see Figure 6.

The flange 8' of this fl er plate 5' is formed with an opening 19 tirough which is extended the wire flyer arm 20, the inner end of which is bent into circular formation for engagement within a circumferential channel of the sleeve 7 formed by rabbeting the periphery of the flange 18 thereof. The extreme inner end of this wire arm is formed with a hook 21 for engagement with the wire arm. proper as indicated more clearly in Figure 5 so as to prevent the expansion of the ring-like end of the H er arm and its consequent disengagement rom the sleeve 7', which sleeve carries a set screw 22 for the purpose of permittng of the rigid attachment of the flyer to the'spinning and twisting unit spindle.

In opposed relation with the opening 19 of the plate flange 8' through which the wire arm 20 passes and at opposite sides thereof the said plate 5' is formed with a pair of struck out tongues 2323 for the pur ose of permittin of the attachment of a yer arm counter alancing weight 24 thereto, 71 which weight is in the form of a length of wire 1preferably of lead or other weight ma teria It will thus be seen that I have provided two forms of flyer construction, each of 84 which is well adapted for all the purposes heretofore designated, and even though I have herein shown and describedthese forms of the invention as consisting of certain detail structural elements it is nevertheless to 8 be undertsood that some changes may be made therein without effecting the spirit and scope of the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Let- 0 ters Patent is 1. In a flyer for thread spinning and twisting units, a member constructed for rigid attachment to the unit spindle and having a lateral, apertured flange, an arm 9 extending through said flange aperture and radially from said member and a counterbalancing weight associated with the member in opposed relation with respect to the arm.

2. In a flyer for thread spinning and twisting units, a member constructed for rigid attachment to the unit spindle and having a lateral, apertured flange, and an arm extending through said flange aperture and radially from said member and having its inner portion detachably connected with the member.

3. In a flyer for thread spinning and twisting units, an apertured member constructed for rigid attachment to the unit spindle, an arm extending through and radiall from said apertured member and readily detachably connected therewith, and a counterbalancing weight associated with the member in opposed relation with respect to the arm.

4. In a flyer for thread spinning and twisting units, a member constructed for rigid attachment to the unit spindle, an arm extending radially from said member and readily detachably associated therewith, a counterbalancing weight associated with the member in opposed relation with respect to the arm, and a single member for facilitating the attachment of the counterbalancing weight to said first mentioned member, and for the securing of said member to the unit spindle.

5. In a flyer for thread spinning and 1 6. In a fiyer for thread spinning and twisting units, a circular body having an opening in the center thereof to permit the disposition of the body upon the unit spindle, a collar upon the inner side of the body and coaxial with said opening, an arm extending radially from the said body and being so bent at its inner end as to engage.

around said collar and a counterbalancing weight associated with the body in opposed relation with said arm, and a single member for securing the counterbalancing weight to the body and said body to said unit spindle.

7 In a flyer for thread spinning and twisting units, a member constructed for rigid attachment to the unit spindle, an arm extending radially from said member and formed at its outer end with aneye having a free end portion and a thread guide sleeve removably arranged on said end portion of the eye of said arm.

8. In a flyer and in combination, a member having an inner portion and also having a flange, an arm extending from the flange of vand detachably connected with the inner portion of the member, and a counterbalance weight carried by the member within the flange thereof.

9. In a flyer, and in combination, an arm having at its outer end an eye and also having a free end portion normally maintained by the inherent resiliency of the arm against the major portion of the arm, and a thread guide sleeve removably arranged on said end portion of said eye.

10. In a fiyer, and in combination, a member, anarm carried by and extending from the member and having an eye, and a thread guide arranged on and receiving a portion of said eye.

11. In a flyer, and in combination, an arm having an eye, and a thread guide sleeve removably arranged on and receiving av portion of the arm forming said eye.

12. In a flyer and in combination, a member having an innerportion and also having a flange surrounding and spaced from said inner portion, and an arm extending from and engaged with the flange of the member and detachably connected with the inner portion of the member, said arm extending in a substantially radial direction through the space between the inner portion of the member and the flange thereof.

In testimony whereof I afiix my signature.
